Self-excited wave oscillations in a water table
Abstract
An experimental investigation has been performed on self-excited wave oscillations on cavity, spike-tripped, and inlet models in a water table. Buzzing was generated by positioning the models at a small angle of attack with respect to the free stream flow. The hydraulic analogy was used to compare the results obtained in water to results obtained in a gas. High speed and real time photography was used in the experiment. The frequency of oscillations in water and air were consistent with the hydraulic analogy. Numerical solutions of the phenomenon were also obtained.
